    I'm on tmobile and used Sn0wbreeze on 4.3.3. Considering going to IOS 5. I believe i have old bootrom but I will triple check. I had no idea that bootrom and baseband were different until today. Is it the same process I used last time... Sn0wbreeze and then UltrasnOw to unlock? I heard about problems with gamecenter. Is there something else I
    need to do. Thanks.

    Yep, same process. I don't remember hearing anything about issues with gamecenter, sorry I can't answer that question.

    Jailbreak iOS 5 On Windows Using Sn0wbreeze 2.8b8 | Redmond Pie

    Here's a guide in case you forgot how to. Remember, iOS 5 jailbreaks are all tethered. You may install from Cydia the BigBoss Semi-Tether tweak to make it a semi-tethered jb if that is something you'd be interested in.

    3GS old bootrom is indeed untethered on 5.0.

    Thanks. One more thing. I'm on 5.13.04 and has assumed I was on old bootrom. I found out today that baseband and bootrom are different. I downloaded f0recast to check and for bootloader it says 6.4_M3S2. I've read that 359.3 is the old one. So is the 6.4 the 359.3.... I don't quite understand.

    f0recast won't tell you your bootrom. Download idetector to find that out.

    Thanks. I downloaded it and it says i have to go into dfu mode. I'm not ready to upgrade yet so can I easily get out of dfu mode?

    Yeah to get out of DFU, when youre finished, just hold home and power for 10 seconds, release, then power on as normal.

    Hey I am having issues detecting baseband. Idetector does not work. I keep getting a message that it can't detect my device. I then tried to look at device manager and it does not give me the info. My phoned is definitely in dfu mode. I did notice that when i connect to itunes, it needs to check for a carrier update each time which I allow. I have itunes

    Any other ideas about how to check? I have 2 3GS' and this happens on both phones. Thanks.

    I used USB view and I was able to get bootrom. If you are on windows sp3, you might need it.

    iTunes shouldnt be offering you a carrier update if you are in DFU.
